A western stretch of the Intercounty Connector, MD 200, opened February 23, 2010, between I-370 and MD 28. It features a short tunnel and automated full-speed electronic tolling.
Apparently MD 200 will pick up its mileage points and exit numbers from I-370, which will end at the Shady Grove Metro. All traffic was routed up a temporary ramp to MD 28. The portion east of MD 97 to I-95 was opened November 22, 2011.

The contracts were awarded in four sections for the ICC itself, plus a contract for an adjoining collector ramp on I-95.
There are already bridge columns and abutments at I-95 and US 29, as well as the western end at I-370.
The ICC will be Maryland's first experience with congestion pricing and demand-based toll rates.

Montgomery County political and business leaders favored the ICC proposal,
although Governor Glendening withdrew his endorsement for the project during
his 1998 re-election campaign. At one point, Glendening favored the sale of
the land set aside for the ICC. However, the plans were again revived under
Governor Ehrlich upon taking office in 2003. The ICC received federal approval
on May 30, 2006, and subsequently construction moved forward. The defeat of
Ehrlich and return of Democratic state monopoly in the 2006 elections raised hopes once again for ICC opponents, but Governor
O'Malley stayed the course, and remained in favor of completion.

There's a MD 201 sign as you enter Maryland on the B-W Parkway. However, 201 leaves on the first exit,
and MD 295 doesn't officially start until the end of federal maintenance at MD 175. MD 201 north of 450 in Bladensburg was formerly
numbered MD 205.

Provides an eastern bypass of Waldorf and the current 301-5 junction. The 205 designation will probably be abandoned
in the very near future, to become the new MD 5. It's already reflected on official maps, but as of mid-August 1998 the 205 signs
were still there.

This one was swallowed up by 208 when the latter was apparently shifted around on some neighborhood streets. At one time 38 St/Ave were
named Eldrige & Barney Streets. The names of the streets seem to change and shift like desert sand.

It's surprising this one is still on the books; 208 is just a few streets running jaggedly along through
the close-in incorporated suburbs of DC. From the one trip I made there some years back, it is all two-lane streets with curbs and no shoulder.
Between US 1 and US 1 Alt was once numbered as MD 206. MD 208 isn't all state maintained, there's some municipal maintenance here on the part of
Brentwood. It was all fairly well marked if things haven't changed since
my last trip.

MD 213 is the fourth longest state route, and eleventh overall at 68.25 miles. It was created
when US 213 was decommissioned sometime in the late 1970s. US 213 until 1949 also consisted of all of current US 50 south of Wye Mills to Ocean City. The
northern end was at US 40 in Elkton. When the US designation was dropped, MD 280 was absorbed into the new state route. Route 280 was the part of the
current route north of US 40 to the Pennsylvania border.

Before the completion of its final link just northwest of its interchange with I-95, MD 216 was a broken route. The gap was bridged by unnumbered Leishear Rd.

It was broken in more ways than that. MD 216 once ran east of Laurel through Maryland City to the area near Fort Meade, this having been broken by the building of the
B-W Parkway. East of the B-W Parkway though, a signed piece of MD 216 connecting with MD 198. It leads to an abandoned
children's mental hospital run by the district of Columbia. A newspaper article once told of some unmarked graves...ghost stories, anyone?

This stub's junction with MD 198 was the scene of a light plane crash on May 4, 2007, which some news reports mentioned as being 'on Route 216'.
Other than they busy adjacent MD 198, this road was the only clear landing site, otherwise it's surrounded by woods.
